SC Bypass Framing Slide-Clip Connector

Ideal for high-seismic areas, Simpson Strong-Tie® SC connectors are the optimal solution for slide-clip bypass framing. SC clips are often welded to the structure in high-seismic zones, but they also feature anchorage holes so that concrete screws or powder-actuated fasteners can be used to attach the clip to the structure. In addition to anchorage versatility, the SC clips include "No-Equal" stamps at the center of the slots to ensure proper shouldered screw placement. SC connectors are manufactured using heavy-duty 10- and 12-gauge steel to provide exceptional resistance to in-plane seismic load.

Key Features

The clips come in lengths of 3 1/2", 6" and 8" for use with 3 5/8", 6" and 8" studs, respectively

Embossments in the bend line provide increased strength and stiffness in the F1 and F2 load directions, but are positioned towards the center of the clip so that 1 1/2"-long welds can be applied at the top and bottom of the clip

Load Tables

SC Allowable Connector Loads

SC Allowable Connector Loads are also limited by the SC Anchorage Load tables below. Use the minimum tabulated values from the connector and anchorage load tables as applicable.

See illustration for fastener placement when using only two shouldered screws to the stud.

Tabulated F1 loads are based on assembly tests with the load through the centerline of stud.Tested failure modes were due to screw pullout; therefore compare F1 against FP calculated per ASCE 7-10 Chapter 13 with aP=1.25 and Rp=1.0.

F1 loads are based on maximum stand-off distances of 1" or 1 1/2" as shown. Other loads are applicable to a 1" stand-off for SC32 and 1" or 1 1/2" stand-off for SC62 and SC82.

SC Allowable Anchorage Loads to Steel

Allowable anchorage loads are also limited by the SC Connector Load Table above. Use the minimum
tabulated values from the connector and anchorage load tables as applicable.

Allowable loads for #12-24 self-drilling screws and PDPAT powder-actuated fasteners are based on installation
in minimum 3/16" thick structural steel with Fy = 36 ksi. PDPAT values are also provided for A572 steel. Values listed
above may be used where other thicknesses of steel are encountered provided that the fastener has equal or better
tested values into thicker steel. It is the responsibility of the Designer to select the proper
length fasteners based on the steel thickness installation.

For screw fastener installation into steel backed by concrete, predrilling of both the steel and the concrete
is suggested. For predrilling use a maximum 3/16"-diameter drill bit.

Allowable Titen HD® Anchorage Loads into Concrete with SC Clip

Allowable anchor capacities have been determined using ACI 318-14 Chapter 17 calculations with a minimum concrete compressive strength (f'c) of 3,000 and 4,000 psi in normal-weight concrete. Tabulated values shall be multiplied by a factor (λa) of 0.6 for sand light-weight concrete.

Allowable Stress Design (ASD) values were determined by multiplying calculated LRFD capacities by a conversion factor, Alpha (α), of 0.70 for seismic load and 0.6 for wind loads. ASD values for other combinations may be determined using alternate conversion factors.

Tabulated allowable ASD loads for Wind and Seismic in SDC A&B are based on using wind conversion factors and may be increased by 1.17 for SDC A&B only.
